Traumatic brain injury in children and adolescents: psychiatric disorders at one year.
Factors predictive of psychiatric outcome in the second 6 months following traumatic brain injury (TBI) in 43 children and adolescents were assessed prospectively. The outcome measure was the presence of a psychiatric disorder not present before the injury ("novel"). ⋯ Severity of injury, when reclassified as severe versus mild/moderate TBI, significantly predicted novel psychiatric disorders. These data suggest that some children, identifiable through clinical assessment, are at increased risk for psychiatric disorders following TBI.

Is delirium different when it occurs in dementia? A study using the delirium rating scale.
The authors studied 61 geropsychiatric patients with delirium from a cohort of 843 consecutive admissions to a geriatric clinical research unit. A central study goal was to assess how the presence of dementia affected the presentation of delirium. Eighteen delirious (D) and 43 delirious-demented (D-D) patients were compared on the Delirium Rating Scale (DRS), Mini-Mental State Examination (MMSE), Brief Psychiatric Rating Scale (BPRS), and EEG. ⋯ DRS items were similar in the two groups except that D-D had more cognitive impairment than D. An exploratory principal components analysis of DRS items identified two core factors. The authors conclude that the presentation of delirium in the setting of concurrent dementia is very similar to delirium without dementia, with subtle differences probably attributable to dementia.
